摘　　要：核仪表系统(RPN)是核电厂仪控系统的重要组成部分。本文介绍了AP1000功率量程中子注量率正变化率高紧急停堆的基本原理,对该紧急停堆信号触发与停堆定值、时间常数、功率变化率的关系进行了分析,并以MATLAB软件为平台,基于弹棒事故和正常运行瞬态两种典型工况的瞬态过程数据,对AP1000功率量程中子注量率正变化率高紧急停堆定值和时间常数的设计进行了仿真验证。Nuclear instrumentation system is an important part of safety instrument and control system in nuclear power plant. This paper introduces the principle of AP1000 power range high positive neutron flux rate reactor trip, and analyses the relationship of the trigger of this reactor trip with setpoint, time constant and power rate. The design of setpoint and time constant for power range high positive neulron flux rate reactor trip is verified on MATLAB software platform based on the transient process data of rod ejection and normal operation transient also.
